<p><span style="font-size:14px"><span style="font-family:Arial,Helvetica,sans-serif">The present study was designed to determine the species diversity and composition of zooplankton of three lentic water bodies from district Fatehabad, Haryana, India. The assessment was done from December, 2012 to November, 2013. A total of 32 species of zooplankton were identified from this study. Rotifera recorded the highest number of species (13) followed by Cladocera (11), which in turn was followed by Copepoda (6), Ostracoda and Insecta (1 species each). Maximum number of zooplankton species (26) were reported from Chilli lake, whereas, Daulatpuria Pond reported the minimum number of species (18). Dominant zooplankton reported at study sites were <em>Nauplius sp</em>., <em>Mesocyclops </em>sp., <em>Phyllodiaptomus </em>sp., <em>Brachionus</em>. <em>falcatus</em>, <em>B. quadridentatus</em>, <em>B. caudatus</em>, <em>Diaphanosoma </em>sp. and <em>Chironomous</em> larva. Presence of a number of pollution tolerant species of zooplankton such as <em>Brachionus quadridentatus, Keratella sp., Ceriodaphnia, Miona </em>sp<em>., Mesocyclops </em>sp<em>., Monostyla </em>sp<em>.</em>and <em>Diaphanosoma </em>sp. indicates the eutrophic nature of the water bodies.</span></span></p>
